lVlALT-TURNiNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 390,299, dated October2, 1888.

(No modell To @ZZ whom. it may concern:

Be it known that we, PAUL. Hausen, Sr., and ROBERT H. DEPEW, bothcitizens of the United States, and both residing at St. Paul, in thecounty of Ramsey and State of Minnesota, have jointly invented certainnew and useful Improvements in Malt-Turning Apparatus, of which thefollowingisaspecificatiou.

rlhis invention relates to machines or apparatus for turning malt inmalt houses, kilns, and similar locations; and it consist-s in theconstruction, combination, and arrangement of parts, as hereinaftershown and described, and specifically pointed out in the claims.

In the drawings, Figure l is asectional side elevation. Fig. 2 is across-sectional view on the line x 00 of Fig. l, with the drivingmechanism removed. Fig. 3 is an enlarged crosssectional detail of one ofthe armed turning rollers "and brushes, illustrating more fully thedetails of the construction.

A represents the floor of the malt house or kiln, having curved upturnedends A2, and with tracks A3 along the upper edge of its sides A". Onlyone of the sides A" is shown in Fig. l; but the two sides will beprecisely alike, and will each be provided with its own track A3, asshown in Fig. 2.

B represents frames suspended from the tracks AJ by grooved rollers B2,and adapted to support a shaft, B, preferably formed of gas or othertubing to secure strength and lightness. Each of the tracks will beprovided with one of the frames B', so that each end of the shaft B willbe properly supported and adapted to be carried back and forth over thedoor A when the frames B are moved back and forth along the tracks.

Upon opposite sides of the shaft Bn boards D are secured in sections,the edges of the boards being armed with curved metal blades a, andwith'sections of brushes E, pivotally connected to the shaft between thesections of boards D, as shown. The edges of the blades a do not quitetouch the floor A when the shaft B" is revolved; but the brushes areadapted to come in contact with the iioor, so that the thin layers ofthe malt, which the blades vfail to reach, will be swept up by thebrushes.

The sections ofthe boards D will be arranged in progressive angularpositions, so that the blades a will act one at a time upon the malt andlift only a small portion at a time, no two of the blades being inoperation at the same time. By this means the strains upon the shaft aregreatly reduced, enabling a longer shaft to be employed without a centersupport. The brushes E are also arranged in sections, as shown, eachbrush being onehalf the length of tlie'sections of the boards D and notopposite each other, as shown, so that the brushes are in operation onlyone-half as much as the blades a, which is sufficient to accomplish thedesired results. rlhe brushes will be long enough to rest on the edgesof the boards D or the backs ofthe blades a, as shown in Figs. l and 3,when thrown from side to side, the pivoting of the brushes being a veryimportant feature of our invention.

Vhen the shaft B is revolved and drawn across the malt door or kiln, atthe same time the blades a, as before stated, each gathers up a smallquantity of the malt and clcvates it over the shaft and deposits it onthe other side. This action causes the brushes to be dragged across thelicor, as shown in Fig. l, and sweep the floor clear of the malt whichthe blades a do not reach, and, being carried upward and over the shaftby the revolution of the latter until they are past theeenter of gravityof said shaft they (the brushes) will suddenly `fall over and strike thefloor with considerable force and produce a sweeping effect upon themalt next the floor, while at the same time the falling of the brushessuddenly increases the weight on the side of the shaft opposite to theactive side of the blades a, and greatly assists the latter in elevatingits load of malt and decreases the power required to revolve the shaft.The brushes thus adapt themselves to the inequalities of the floor, anddo not exert a lifting force, as they would i if they were rigidlyattaehed to the shaft 5 but exert a sweeping force, which sweeps thelower strata ofthe malt forward, so that it may be caught by the bladesa and elevated over the shaft. The action of the brushes when thusarranged is very effective and complete, enabling every particle of themalt to be picked up and elevated over the shaft, and thus turned77every time the shaft is drawn back and forth over the door.

rlhe blades and brushes are shown arranged IOO to act both when theshaft is being drawn backward and forward over the floor, the brushesacting all the tinie,while 'only one-half of the blades are active atthe same time.

On the faces of the boards D, between the blades a, are arrangeddouble-inclined plates D', whose function it is to cause the malt whenfalling from the blades a to be thrown backward away from the shaft uponthe mass of the nialtjust turned, and not fall down again beneath theshaft. This is also an important feature of our invention, andeffectually prc vents any tendency of the recently-turned malt to fallbeneath the shaft again and come in Contact with the unturned malt.

The mechanism for moving the shaft B back and, forth along the tracksand revolving it at the saine time is the same as that shown in ourapplication for a patent, Serial No. 251,505, filed October 5, 1887.

The edges of the blades a will be formed with teeth a', which serve toseparate the particles of the sprouts7 from the malt and disconnectadhering` masses.

Having thus described our invention, what we claim as new isl In amalt'turning apparatus, the combination of a revolving shaft, bladeshaving curved edges and secured upon opposite sides of said shaft, andbrushes p-ivoted upon opposite sides of the shaft in the spaces betweenthe curved edges of said blades, substantially as described.

2. In a malt-turning apparatus, the combination of a revolving shaft,blades secured upon opposite sides of said shaft, and formed with curvededges a and double-inclined plates or central portions, D', between theinner faces of said blades, substantially as described.

In testimony whereof we have hereunto set our hands in the presence oftwo subscribing witnesses.
